MEASURING ArrnnA rUs.

Application filed June 27,

T all whom. it may concern: v Be it known that I, SYLVANUS waste or smearing of the substance and with maximum rapidity as compared with former means for bottling viscid liquids.

An object is to provide safe ano lconvenient means for bottling a certain viscid po1- .sonous ant paste composition.

The invention'i's not limited in its use to measuring and bottling viscid fluids but may be applied to measuring other materials and products that are adapted to flow and the stream of which canbe cut off. Simplicity andcl1eapness of construction and certainty of action are further objects.

Another obj ectis to provide an apparatu adapted to the purpose above stated, and which will fill two containers at each cycle ofoperation and will automatically bring the containers into filling position before filling,.and move them out of filling position after filling, and so on throughout any desired period of operation. Another object is to make provision for adjustingthe measuring devices todeliver. various sized charges.

Other objectsand advantages may appear from, the accompanying drawings, the subjoined detail description and the appended claims.

, 3 at each revolution of the shaft 1.

showing the inlet closed and outlet open as crank pinion is journaled ona stud at which projects from a support 5 and said pinion is provided with a crank pin 6, that operates a connecting rod 7 and is thereby connected to the rock arm 8, of a rock. shaft 9 which is journaled in bearings '10, 11, that are carried by the table 12, upon which the support 5 is mounted. The. rocking arm 13 of the rock shaft 9 is operably connected through pin and slot connection 14, 15, and lever 16,

' and around a second drum 23. Said drums with a pawl 17 adapted by spring 18 to engage teeth 19 of a ratchet wheel 20 that 1S 'fixed to the drive drum 2]. which drives a belt 22 that is bent around said drum 21 are mounted respectively on horizontal shafts 24, 25, carried by bearings 26, 27,

- that are supported by a. base formed of the table 12, the top of which is flat to form a guide for the upper limb of the belt 22 for aconsiderable length to support trays 28, each of which is provided with seats 29 for receptacles 30 that are to receive the measured liquid. Said seats are equal in width to the respective diameters of the receptacles 30 and are equal in length to a multiple of such diameters, so that when a seat 29 is filled, it will contain a row of receptacles extending from end to end ofthe tray," the peripheries of the end receptacles being tangent to the ends of the tray.

By arranging the receptacles tangent to each other in the tray a greater number of such receptacles (diameters being equal) are enabled to pass under the filling means per foot length of conveyor,than in devices of this character heretofore known.

The ratchet teeth 19 are proportional to the diameter of the respective receptacles,

so that at each operation of the pinion 3 by the mutilated gear 2, the belt 22 will be moved forward a step equal to the diameter of the receptacle.

That is to say, the carrier comprises the belt 22 operable on the track formed bythe level surface of the table 12, and removable trays 28. Said trays are respectivelyprovided with two elongate receptacle seats 29 I that terminate at the ends of the trays where they are provided with retainers 31; and said trays are adapted to accommodate an exact number of receptacles 30 between said retainers which are spaced apart, so that when the seats are supplied with the full quotaof receptacles, the peripheries of the end receptacles will be tangent to the ends of the trays. The receptacles are preferably round in plan as indicated in Fig. 2. The trays may be flat boards and the seats 29 are preferably depressions which may be grooves cut in the surface of the trays, the inner walls of the retainers being curvilinear as indicated at 31 to conform to the periphcries of the end receptacles 30.

The step by step mechanism provided to operate the belt 22 is thus adapted to move two continuous rows of receptacles along the table with considerable periods of rest between the successive movements to allow the receptacles to be charged; and the belt may be supplied with trays of empty receptacles at one end; and trays of filled receptacles may be removed from the other end of the table without interrupting or interfering with the step by step movement. The mutilated gear 2 is adapted to cause one com-- plete revolution of the pinion 3 and crank pin 6 during a minor portion of the revolution of the master shaft so as to comparatively prolong the period of rest.

The pawl 17 is arranged to act downwardly upon the inner side of the ratchet wheel 20 thus to cause the top limb of the belt 22 to travel toward the second drum 23 during a portion of each revolution of the master shaft 1.

The teeth of the mutilated gear 2 equal the number of teeth on the pinion, so that at each revolution of the master shaft 1 there is one complete operation of the pawl 17 .to move the drive drum 21 and the belt 22 a step equaling the space of one tooth, and the diameter of each receptacle is equal to the length of one step of the belt.

In Fig. 13 the tray 28 is shown as exactly equal in len th to ten receptacle diameters; and the seats 29 are equal in width to one. and in length to tenreceptacle diameters and I are conformed at their ends to segments of the peripheries of the receptacles.

The driving pulley 32 is fixed to the master shaft 1 and is driven by a belt33 which may beshifted by means of the belt shifter 34 onto the idler that is journaled on the master shaft. 2

By the mechanism above described the belt on the conveyor is adapted to remove and. emplace receptacles two by two beneath charging; housings hereinafter set forth.

The further end of the master shaft 1 is journaled in a section 36 of the supporting frame, which comprises the base 12 and the upright supports formed of sections 5, 36 and 37. A mutilated gear wheel 38 is fixed to the master shaft l and is'provided with disalined revoluble toothed segments 39, 40,

each of whichis adapted tooperate two-oscillating toothed segments. The revolving;

toothed segment 39 successively engagesthe segments 41, 42, on the arms. 43, 44, respectively, of thero'ck shafts 45, 46, that are j ournaled in the sections 36, 37. The revolving toothed segment 40, successively engages the oscillating toothed segments 47, 48 of the oscillating arms-49, 50, that are respectively fixed to the rock shafts 51, 52 which ing segments are in pairs and the oscillating segments of each pair are connected to-, gether so that the operation of one adjusts .theotherinto position'tobe operated, and

vice versa.

Each-revolution of each revolving toothed segment will operate two of the oscillating segments, and each revolution of the master shaft oscillates all the rock shafts. The toothed segments are on opposite sides of the periphery otthe wheel 38, and the oscillating segments are spaced apart, so that the operation of each oscillating segment will occur when the otherIsegments are at rest. The segments 47 and 48are arranged on opposite sides of the. wheel 38 and'are connectedto each other through adjustable connecting rods 53, 54, respectively that are pivotally connected to the central arm 55 of a three-armed walking beam ,bell crank which is provided with horizontal plunger arms 56,57, and is fulcrumed at 58 to a stationary support 59; The walking beam plunger arms 56, 57, are respectively connected jby adjustable rods 60, 61, to hollow trunk plungers 62,63, towhich the connecting rods are pivoted at 64, 65, so that upon the oscillation of the walkingv beam the segments may be made by any suitable plungers will be operated.

Such plungers are cylindrical and operate in cylindrical shells 66, 67, respectively, that snugly fit rotatably in the housings 68, 69. Said shells 66, 67 are provided respectively 7' with lateral intake ports .70, 70 and with outlet ports 71, 71. The housings 68, 69-

constitute port closing means and are provided with inlet ports 72, 72 and with outlet ports 73,73. -The plunger arms 56, 57 of the walking beam are of equal length and the plunger rods 60, 61 reciprocate the plungers 62, 63-alternately in their oscillatory. shells. through the oscillating rocker arm segments 47 and 48 operated by the toothed revolving segment40.

reciprocating rack g It is-understood that the connection be- ''tween the oscillating segments of either Such reciprocation is effected Referring to-Fig. 4-it will be seen that the oscillating segment 47has been rocked to the the walking beam is at rest and will so remainuntil said toothed segment 40. engages the oscillating segment 48, at which time the right by. the toothed segment 40 and that walking beam will be rocked to the left by the connecting rod 54.

Durlng this period of rest the revolving toothed segment 39 will operate the oscillating segment 41, thereby operating the connecting rod 7.4 that is connected to the horizontalrack 7 5, the teeth of which engage with the toothed rims 76, 77 that are fixed respectively to the shells 66 and 67. Said rack ismounted in a guideway 68 and is connected by a connecting rod 78with the oscillating segment 42. v It is thus seen that the oscillating toothed, segments are arranged in two couples one couple comprising the oscillating segments 41, 42, oppositely arranged relative to the shaft 1, and the other couple comprising the oscillating segments 47. 48, also oppositely 6 arranged relatively to the shaft 1; andthat the tour oscillating segments 1 are spaced apart about theshaft so as to be successively operated by the respective revolving segments. The couple 41, 42'is operated by the revolving segment 39 while the'couple 47, 48 of oscillating segments is o revolving segment 40.

The oscillating segments 41, 42 of the first couple are connected together so that the operation of one efi'ects the operation of the .other'and this is likewise true with regard to the second couple formed of oscillating segments 47,. 48. the segments '47-, 48, comprises'the connect- I aerated by the The connection between ing rods 53, 54, connected by-apin 55 with 1 the oscillating arm 55 of the walking beam. The connection between the oscillatmg segments 41, 42 comprisesth'e connecting rods 74,78, and the pins 75 connected to the couple andthemechanism operated by such means, and such means mayjbe adjustable 'for the purpose of adjusting the apparatus to increase and decrease the amount of liquid'in each charge. In the form shown, the rockshafts 45, 46,

151, 52 are provided with transmitting arms '79, 80 and 81, 82 respectively.

'tion alsooperates the oscillating segment 42.

through the medium of the connecting rod 78,

and adjusts said segment to its gear receiving position ready to receive andbe acted on by the revolving toothed segment.

It will beparticularly noted that the re.-

volving segn1ent' 4O' has passed the oscillating segment 47 and is advanced toward the rock arm segment 48, which segment 48 is I in position to receive the revolving segment .40 and to thereby be operated to the left as the segment 40 passes it. The segment 39 is just in engagement with the oscillating segment 41 and upon further revolution will shift segment 41 to the right which will shift segment 42 to the right into a position relative to the segment 39 that corresponds to the relative positions of 39 and 41 shown in solid lines in Fig. 4. This movement is effected during the transit ofjthe segment 39 across the toothed face of the oscillating segment 41 and such movement shifts the rack 7 5 to the right in Fig. 4, thus oscillating on their vertical or longitudinal axes, both ways inactive while the rack of the shells 66, 67, sufiiciently to cause the side wall of the charge shell 66 to cut off the inlet port 72 of its housing and to then cause the discharge ports 71 and 73 to register so as to open the outlet port.

It is thus seen that the walking beam is connected through the connecting rods 53, 54. and their connections, with oppositelyarranged oscillating segments 47, 48; and the rack 7 5 is operated by connection through the operating rods 74, 78, with the 30p oscillating segments 41, 42, and therefore, at

to first close the outlet and then open the inlet of one shell at one period and likewise to first close the outlet and open the inlet of the other shell at another period, and that the rod 53 will operate the walking beam to cause suction in the shell having its'inlet open and its outlet closed, and to cause pressure in the shell having its inlet closed and outlet open; and vice versa; so that each revolution of the shaft isinvari-' ably accon'ipanied by a succession of operations causing simultaneous suction into one shell and expulsion from the other shell at one time, and vice versa, at another time.

, A supply pipe 179 leading from a source of'supply, not shown, is connected by supply branches 180, 181. with the housings 69, 63, respectively, so that whenever suction is applied to either of the shells, liquid may be supplied to such shell from the supply pipe 79; and when pressure 1S applied in such shell its communication with the source of supply is cut ofi and said pressure is effective to discharge the liquid forcibly through the outlet. p

The construction shown is such that when the mutilated gear 2 operates the pinion 3 to move the belt 22, and advance a set of empty receptacles into filling position, the arms 56, 57 of the walking beam and also the rack 75 are idle; and the construction and arrangement and operation of the various points is also such that when the arms 56, 57 are actuated, the belt 22 and rack 75 are idle; and whenthe rack 75 is actuated the belt 22 and arms 56, 57 are idle so that the various parts are operated intermittently without interference. After the belt 22 has been stepped forward to bring an empty set of receptacles into filling position beneath the outlets of the housings, the belt remains stationary and the walking beam remains inactive while the rack ,7 5 is shifting to the right in Fig. 4, thus oscillating the shells so as to close the inlet and open the outlet of the filled shell and to open the inlet and close the'outlet of the empty shell 67. WVhile this is being accomplished the walking beam and belt are inactive; then the walking beam 55 is operated to the left bythe revolvin segment .40 oscillating the oscillating segment 48 with obvious results, and so on. i p

By these means each revolution of shaft 1 causes the successive charging of two receptacles and the shifting of the charged receptacles from, and two empty receptacles to, filling position.

Attendants will place the trays of empty receptacles on the belt and remove the trays of charged receptacles from the belt as the work proceeds and since the peripheries of the end receptacles of each row in a filled tray are tangent to the ends of the tray,

respectively the rows of empty receptacles pass in continuous and unbroken succession under the outlets ofthe chargers.

The bottoms of the housings and shells are thin so that adhesion of the viscid liquid thereto is slight; and since the outlet ports are small, the liquid is ejected therethrough with considerable force. In consequence of the construction andoperation stated, there is no dripping of liquid to smear the rims or the outsides of the receptacles.

The chambers of the shells are made of ample size and the amount of liquid discharged at each stroke is determined by the length of stroke of the plungers. Such length of stroke is regulated through the length adjustment of the rocker arms 79, 80, 81 and 82. In the form shown each arm comprises threaded telescoping members 83. 84. The member 83 is fixed to its rock shaft by a set screw 85 and the member 84 is pivoted to its connecting-rod, as therod 74, for instance, by a pin 86.

The connecting rods are sectional, each comprising end sections 87, 88 connected by a turn-buckle 89 with a locking set screw 90.

lVhen the parts are assembled they are not easily put out of adjustment and the purpose of this is to avoid variations of charge so that the receptacles will be uniformly charged unless the apparatus is intentionally readjusted. V

Suitable means are provided to prevent the oscillations of the shells from changing the adjustment of the plungers. To this end. jam nuts 91 are provided onthe rod sections 92 to jam against the socket sections 93 of the connecting rods 60, 6 1.
